COMBINED SASH-SILL AND J'AMB COVER.

Application filed January 11, 1915. Serial N 0. 1,586.

To all whom it may concern:

Be it known that I, GEORGE W. DAVIS, a citizen of the United States,residing at Lincoln, county of Lancaster, and State of Nebraska, haveinvented certai new and useful Improvements in Combine Sash-Sill and Jamb Covers, of which the following is a specification.

My invention is particularly designed as a glass or pane holding meansfor store front constructions and it is thus illustrated in thedrawings,but it is susceptible of other uses and adaptations. It is within thespirit and scope of the invention to provide ventilat ing and drainingmeans in connection therewith, but the invention is not limited thereto.

My object is to provide a simple, relatively inexpensive, and easilyinstalled combined clamping strip and sill cover of improvedconstruction and whose parts are combined with the wooden sill and aback strip in an improved manner, effecting improved, beneficialresults. i

The manner in which the clamping strip, side and back strip arecombined, enables them to be shipped together in: such a state that theconstruction can be simply mitered and nailed onto the building where itis to pearance of the store front.

' The invention is fully set forth hereinafter and recited intheappended claims.

In the accompanying drawings: Figure 1 is a perspective, partly insection, showing the invention in use and a portion of a store front;Fig. 2, a detail perspective, with parts broken away, showing the'innertension plate; Fig. 3, a similar view of the clamping strip and sillcover which are preferably in a single piece; Fig; 4, a vertical sectionof a modification having drainage and ventilating means Fig. 5, ,adetail longitudinally the full length of the strip.

perspective of a portion of'the cover plate of Fig. 4; and Fig. 6, adetail vertical section, illustrating the leverage action of theclamping strip in all forms of the invention and, further, showing arabbeted edge for the main sill and how the cover for the main sill maybe removed.

The wooden sill at the bottom of the store front is shown at 1. For theadaptation of my invention thereto, the sill is provided with alongitudinal channel or rabbet 2 which may be of inverted V-shape, or asa rabbet 2* as in Fig. 6, extending the entire length of its bottomfacenear the outer edge thereof. The glass store front or pane is shownat 3. The back strip't is preferably of wood, although I am aware thatit could be of sheet metal. If of wood, which I prefer, the back strip 4is nailed to the sill 1. If of sheet metal, said back strip 4 may besecured to the sill 1 in any preferred manner. I have found that by theuse of wood for the back strip 4, all expansion or contraction of theglass 3 is taken care 'of better than if sheet metal is used, besideaffording rigidity and solidarity as well as ease of attachment to thesill 1. Whether wood or metal beemployed for the back strip 1, it isprovided with a channel, rabbet or seat 5 for the pane 3 and thearrangement and combination with the other parts is such that the panemay be set from the outside.

The metal sill cover 6 and metal clamping plate 7 are preferably made ina single piece, as shown in Fig. 3. The sill cover 6 conforms to thefront 8 and top 9 of the sill 1 and also to a portion of the bottom 10,the bottom portion being provided with a longitudinally extending beador rib 11 which is received in the rabbet or groove 2, thus holding theparts secured together and forming a metal facin for the under face ofthe sill. The strip, is bowed and may be of the form shown, or of other.appearance, provided the bowed formation is retained. This bowedformation gives the strip 7 a certain leverage, adaptlng it to exert acontinuous pressure on the pane 3 and to conform to any variationstherein. The strip 7 is provided with channels or grooves 12 and 13formed by bends therein, said channels or grooves extending An inneroutwardly bowed extension tension plate 14 of the form shown in Fig. 2,

has longitudinally fiat portions and 16 which are received in thegrooves or chan-' nels 12 and 13. The arch or bow of the touches thefront wall of the wooden strip 4 nor the inner wall of the strip 7, butis in the nature of a diaphragm interposed between said parts.Preferably the lower inner corner of the strip 4 is'beveled or cut awayat 17 to afford entire freedom for the Channeled part 13 to permit it tobe drawn into-said cut away portion 17 so as to afford no impediment tothe yielding or Cushioned clamping action of the channeled part 12 onthe pane 3 under the tension exerted by the tension plate 14. Thistension is effected by screw bolts 18 passing loosely through the strip4 at different points of the length thereof and having theirscrew-threaded ends 19 engaged with screw-threaded holes 20 in thecenter of the tension plate 14. Preferably the holes 21 through whichthe bolts 18 pass, are provided with countersinks for the heads of saidbolts. These holes may be provided with internal sleeves or bushings ornot,-as preferred.

The tensionof the bolts 18 is exerted on the middle bowed portion of theplate 14 and applied against the channeled parts 12, 13, drawing both ofsaid parts inwardly toward the strip 4 and with a leverage on part 12.resulting in a firm, cushioned pressure being applied to the front ofthe pane 3. thus adapting the strip'7 to all variations in the glass 3and also drawing the sill cover against the front and top 8 and 9 of thelieferring to Figs. 4 and 5, in addition to the construction previouslydescribed, I may provide drainage and ventilation holes 22 extendingthrough the sill 1 and strip 4 and opening out at the bottom through onewall of the bead 11 and at the top through a hole 23 in a cover plate 24which may be provided for the strip 4 to prevent moisture from rottingthe wooden strip 4. Holes 25 maybe provided to afford access to thebolts 18. As many drainage and ventilation holes or ports 22 will beprovided, at intervals lengthwise of the structure, as desired.

Fig. 6 illustrates the leverage' action of the strip 7, dotted linesshowing it sprungback from the fulcrum point, seat or base 26 and fulllines, the normal position of said strip, the leverage extending from 26to 12 and being applied at 12 to the pane 3, forcing the latter againstthe wood cushion back strip 4. The bolts 18 are used, as previouslyexplained, but are not shown in this view.

This leverage action is common to all forms of the invention.

Instead of employing the channel 2, I may use a rabbet 2 at the outeredge of the -sill 1 and strip 4. This form of channel 2 may be used onall forms of the invention.

In Fig. 6, I have shown the cover 6 broken away at 6 better toillustrate the location of the fulcrum seat or base 2".

The complete structure may be shipped in such a state that it can besimply mitered and nailed onto all the sides, forming a frame and sashcomplete on the store front or other place where it is to be used andthe pane 3 readily set, thus saving much time and labor heretoforeconsumed in fitting together the parts of store front constructions.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

The combination with a main sill, of a back strip supported therebyhaving a rabbet adapted to receive, support, and form a backing for aglass pane, a sill cover and bowed clamping strip formed in a. singlepiece, said clamping stripbeing adapted to bear against the outer edgeof the pane and having upper and lower rebent portions, a tension platelocated back of the clamping plate and whose upper and lower edges areinterlocked with the rebent portions aforesaid, and fastenings locatedbelow the lower edge of the pane connecting the free central portion ofthe tension plate and the back strip together.

2. The combination with a main sill having a channel in its bottom, of aback strip supported thereby adapted to form a backing for a glass pane,a one-piece metallic sill cover and clamping strip, said coverconforming to the bottom, front and -top of the main sill and having apart of GEO. 1V. DAVIS.
